摘要:
A screening device (e.g. screen plate or screen cylinder) is manufactured relatively inexpensively and easily yet has uniform screening openings (e.g. screening slots) even when of a width of less than 0.5 mm. A plurality of wires having first and second sections (the second sections having base portions and of smaller cross-section than the first sections) are mounted substantially parallel to each other, supported by at least one support bar or ring. The bars or rings have slots formed in a first side surface, and a cavity in open communication with the slots in a second side surface. The wires are fixed to the bars or rings by deforming the wires (e.g. by bending a flap, engagement by a reciprocating tool, welding, etc.) within the cavity, or by deformation of the support bar or ring in the cavity. The screen plate or cylinder is preferably used to screen or otherwise treat a cellulose pulp suspension, e.g. by subjecting the first sections of the wires to a flow of pulp with accepts passing through the screening openings.
摘要:
A method of enhancing the transcription of a gene in a DNA construct incorporated into the genome of a eucaryotic host cell, wherein the DNA construct comprises a structural gene for a desired protein or polypeptide in a gene promoter upstream of the structural gene, comprises providing at least one enhancer element comprising the nucleotide sequence TTC TGA GAA upstream of the promoter, and exposing the DNA construct to lactogenic stimuli. An expression vector, a host cell and a transgenic mammal containing the vector are of interest.

Techniques are disclosed relating to testing logic in integrated circuits using an external test tool. In one embodiment, an integrated circuit includes a logic unit and a self-test unit. The self-test unit is configured to receive an expected signature value that corresponds to an expected output value of the logic unit, and to compare the expected signature value and an actual signature value generated from an actual output value from the logic unit. In some embodiments, the integrated circuit further includes a pseudo-random pattern generator configured to provide an input value to the logic unit, and the logic unit is configured to generate the actual output value based on the provided input value. In some embodiments, the integrated circuit further includes a multiple-input signature register (MISR) configured to generate the actual signature value based on the actual output value and a seed value.

The invention is a system and method for the distribution of recordings of live audio and/or video performances to audience members at a performance. The system comprises means for promptly uploading recordings of performance segments into a database controlled by an order server. An audience member employs a wireless messaging devices such as a cellular telephone to place an order for a recording with a Short Message Service linked to said order server, and, upon arranging for payment of a recording download, said audience member is provided (via a text message to the ordering wireless device) with an internet URL address at which a copy of the recording ordered has been made available for download.
